A simple transmission cavity placed in the output transmission line of a CW Gunn oscillator can be adjusted to allow simple and cheap digital frequency modulation by bias modulation. Transition rates down to 10 ns have been demonstrated. A threshold switching voltage is required so that the circuit has noise immunity.
